Abstract: A pneumatic recoil reduction adapter for use with a barrel and breech of an existing explosives disarmer. The adapter substantially reduces and, indeed, achieves near-total recoil reduction of recoil using venturi-venting rather than damping liquids, spring-damped shot tubes or other unwieldy mechanics. The recoil reduction adapter is formed with a central chamber to seat a cartridge and a plurality of axially extending passages leading outward from the central chamber through a corresponding plurality of radially-spaced venturi nozzles. Upon firing, exhaust gases are vented rearwardly back through the central chamber and outward through the venturi nozzles to offset and thereby reduce recoil forces.
